Like most other D5 pumps this reliability is afforded by the same unique design as the original pump, which contains only one moving part: the magnetically driven spherical impeller spins on a single ceramic bearing, thus extending the life of this pump beyond existing standards. ? The pumps data and speed control is done using the PWM 4-pin connector. By connecting this the pump speed can be controlled via the computers similar to a CPU fan speed. This also allows the safety feature of auto shut down based on RPM feedback if available in your BIOS.
